Abstract
The utility model discloses a high-pressure resistant anti-off ceramic cylinder sleeve which comprises an upper end cap, a lower end cap, a metal outer sleeve, a ceramic inner sleeve, an upper positioning pin and a lower positioning pin, wherein the metal outer sleeve is in hot-pressing connection with the ceramic inner sleeve; the upper end cap and the lower end cap are in threaded connection with the metal outer sleeve, and are positioned via the upper positioning pin and the lower positioning pin; the upper end cap and the lower end cap are in smooth transition with the ceramic inner sleeve; and outer end surfaces of inner walls of the upper end cap and the lower end cap are processed and tapered. With the adoption of the structure, the high-pressure resistant anti-off ceramic cylinder sleeve solves the problem that ceramic parts in the ceramic cylinder sleeve are easy to break and fall off under high pressure, and is widely applied to the industries of oil, geological exploration, chemical industry and the like, greatly prolongs the service life of the product, and lowers the production cost of enterprises.
Description
One, technical field
The utility model relates to a kind of slurry pump with high pressure resistant anti-dropping type ceramic cylinder jacket.
Two, background technique
High pressure slurry pump is oil drilling, geologic prospecting worktable " heart ", and mud slurry pump cylinder jacket is the important composition parts of slurry pump.The mud slurry pump cylinder jacket that uses is divided into bi-metal liner or two kinds of structures of ceramic cylinder jacket at present: because industrial and mineral is very abominable, Metallic cylinder is not wear-resisting, not corrosion-resistant, and working life is very short, and the ceramic cylinder jacket structure is too simple, under high pressure be easy to come off or fragmentation, still can not reach ideal effect.
Three, summary of the invention
The purpose of this utility model is to provide the high pressure resistant anti-dropping type ceramic cylinder jacket that a kind of structure is simple relatively, solid and reliable, wear-resistant, corrosion-resistant, be difficult for fragmentation, long service life.
The purpose of this utility model is achieved in that a kind of high pressure resistant anti-dropping type ceramic cylinder jacket, comprises cover (2) in upper plug head (3), lower end cap (5), metal-coating (1), the pottery, last locating stud (4), following locating stud (6); Metal-coating (1) is that hot pressing is connected with the interior cover of pottery (2) Placement, upper plug head (3), lower end cap (5) and metal-coating (1) Placement are for being threaded and using locating stud (4), locating stud (6) location down, take smooth transition between the cover (2) in upper plug head (3), lower end cap (5) and the pottery, certain tapering is processed in upper plug head (3), lower end cap (5) inwall exterior edge face.
A kind of high pressure resistant anti-dropping type ceramic cylinder jacket plug of the present utility model comprises cover in upper and lower plug, metal-coating, the pottery, upper and lower locating stud; Metal-coating is connected mode with cover in the pottery be that hot pressing connects, upper and lower plug and metal-coating Placement are for being threaded and with upper and lower locating stud location, take smooth transition between the cover in upper and lower plug and the pottery, certain tapering is processed in last lower end cap inwall exterior edge face.This structure has well solved under high pressure frangible, the caducous problem of ceramic component in the ceramic cylinder jacket, and it is widely used in the industries such as oil, geologic prospecting and chemical industry, prolongs the working life of product greatly, reduces enterprise's cost of production.
Four, description of drawings
Fig. 1 is a kind of high pressure resistant anti-dropping type ceramic cylinder jacket vertical profile schematic representation of the utility model.
Five, embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description.
As a kind of high pressure resistant anti-dropping type ceramic cylinder jacket of Fig. 1, comprise cover (2) in upper plug head (3), lower end cap (5), metal-coating (1), the pottery, last locating stud (4), following locating stud (6); Metal-coating (1) is that hot pressing is connected with the interior cover of pottery (2) Placement, upper plug head (3), lower end cap (5) and metal-coating (1) Placement are for being threaded and using locating stud (4), locating stud (6) location down, take smooth transition between the cover (2) in upper plug head (3), lower end cap (5) and the pottery, certain tapering is processed in upper plug head (3), lower end cap (5) inwall exterior edge face.
Claims (1)
1. a high pressure resistant anti-dropping type ceramic cylinder jacket comprises cover (2) in upper plug head (3), lower end cap (5), metal-coating (1), the pottery, last locating stud (4), following locating stud (6); Metal-coating (1) is that hot pressing is connected with the interior cover of pottery (2) Placement, upper plug head (3), lower end cap (5) and metal-coating (1) Placement are for being threaded and using locating stud (4), locating stud (6) location down, take smooth transition between the cover (2) in upper plug head (3), lower end cap (5) and the pottery, certain tapering is processed in upper plug head (3), lower end cap (5) inwall exterior edge face.
